When installed in a corporate LAN, the Ampps doesn't work if it is behind the firewall or proxy server. This is a need for testing environment (by web developers) and if they work for a corporate company cannot use Ammps as the application needs a direct connection to the Internet, when installed the free version.

My suggestion is provide a setting panel during the first setup of the Ampp, where we can input settings for Proxy Server, Internet Gateway or Open Ports in the Firewall. It would help too the network administrators plan their network for the developer teamwork in the company...
